How to solve the problem of China passport being monitored by Vietnamese Immigration Bureau?

I need to consult with the local exit-entry administration office with valid documents. According to the inquiry of the Passport Office, China passport is monitored by the Vietnamese Immigration Bureau, and I need to personally consult with the local exit-entry administration office with valid documents. Passport number is a personal secret, and only when an individual provides a certificate that can prove his identity can the entry-exit administration department help with the inquiry. Passport number, like ID number, serves as a sign to prove identity.
